I'm so downcast. I wanted it to be. Everyone says it is. And on a good day, from low Earth orbit, if you squint, it is, but not from the moon or anywhere farther out. And other things are way more visible.

I found this out while working on this China newsletter I'm working on. (Hmm... internal editor doesn't like a sentence that says "working on... working on") The author of one article had enthusiastically inflated the length of the Long March (it was about 6,000 miles; he had it as 25,000 miles--which would make it longer than the circumference of the Earth!), and that made me think I had better check his facts on the Great Wall. (He didn't claim it was visible from space, but I just thought I'd check that, since I was checking its length and so on...)
